Technology

Solid-state Technology

JRC's new solid-state architecture integrates an advanced signal processing technology that detects and displays information at a new level.
These dedicated signal processing circuits are producing higher capability than a klystron radar or a magnetron radar, greatly exceeding detection performance.
Transmission power of the solid-state transmitter is small compared to the tube type transmitter, but by using the pulse compression technique, it is possible to impart the transmission capacity comparable to that of the tube type radar.

Low maintenance cost
Solid-State Power Amplifier (C-band)

Low Maintenance Cost

The radar integrates a highly reliable solid-state transmitter in place of a life limited klystron or magnetron. The solid-state radar provides higher reliability and performance and will keep maintenance costs to a minimum.
